In the landscape of modern material science, "Excellent Elasticity" is not merely a physical attribute; it is a critical performance metric that dictates the reliability of EV charging systems, 5G infrastructure, and aerospace precision instruments. As a leading OEM manufacturer, Sichuan Kepai New Material Co., Ltd. addresses the industry's demand for materials that combine high conductivity with superior yield strength and fatigue resistance.
Our alloys are engineered to withstand repeated stress cycles without permanent deformation, achieving a balance between Young's Modulus and thermal stability.
Unlike standard spring steels, our high-elasticity copper alloys (like Beryllium Copper and Tellurium Copper) maintain up to 90% IACS conductivity.
Optimized for long-lifecycle applications in relays and connectors, ensuring millions of actuations in harsh environments.
The global shift toward electrification and high-speed data transmission is driving a paradigm shift in material procurement. We have identified several key trends:
Components are getting smaller, requiring materials with higher stress tolerance. Our C17200 Beryllium Copper and C51900 Phosphor Bronze provide the necessary "excellent elasticity" for micro-connectors.
High-current applications generate heat. Materials must retain their elastic properties at elevated temperatures. Our Tellurium Copper (C14500) offers the perfect blend of easy machining and heat dissipation.
The industry is moving away from hazardous elements. We are leading the R&D in lead-free, high-conductivity alloys that meet global environmental compliance without sacrificing performance.
Established in 2017, Sichuan Kepai New Materials Co., Ltd. is a high-tech enterprise integrating research and development, production, and sales. Currently, the factory covers an area of approximately 9,000 square meters. The company primarily engages in the production of strategic emerging new materials, including special copper alloys such as tellurium copper, high-conductivity oxygen-free copper, silver copper, and dispersion copper.
Our R&D team composed of senior industry experts keeps pace with international cutting-edge technology. Through industry-university-research collaboration, Kepai has made breakthrough progress in high-performance tellurium copper, lead copper, and sulfur copper.
From basic materials to high-end customization: pure copper, oxygen-free copper, nickel tellurium copper, tin bronze, beryllium copper, lead bronze, sulfur copper, and chromium zirconium copper.
Rooted in Sichuan, radiating nationwide, and moving towards the world. We have established stable customer bases and long-term partnerships with internationally renowned enterprises.
Advocating "integrity, innovation, collaboration, and win-win." We emphasize teamwork and talent cultivation to create a harmonious and inclusive atmosphere.
Our "Excellent Elasticity" materials are integrated into holistic solutions for global challenges:
Providing high-elasticity contact materials for charging piles and battery management systems (BMS) that ensure consistent contact pressure over 10,000+ plug cycles.
Developing ultra-thin elastic copper foils for signal shielding and high-frequency connectors where signal integrity is paramount.
Utilizing high-performance alloys for plasma cutting electrodes and lithium battery relays, enhancing equipment lifespan and operational efficiency.
